One degree of servo change results in one degree in rudder change at all points in the travel from neutral to full throw. We don't care how far fore and aft the push rod or cables move to get these results.<div><br></div><div>Jim O<br><div><br></div><div><br><div><html>On May 9, 2008, at 6:32 AM, Mark Atwood wrote:</html><br class="Apple-interchange-newline"><blockquote type="cite"><div> <font size="4"><font face="Calibri, Verdana, Helvetica, Arial"><span style="font-size:11pt">Better. But let’s not get gaudy about it...lol<br> <br> The reality is the throw is just more linear. With an arm, even though the attachment point of the cable to the arm still moves in a circular fashion (same as the wheel), the cable is not following the arc. So the angle of the cable is changing, and the relative throw is decreasing as the arm is deflecting.<br> <br> Can you tell??? Well, it’s effectively giving you opposite expo (the arm is). Meaning the throw is more sensitive around neutral. When we used Analog servos...this was actually a good thing. The amount of blow back on our barn door rudders made the first bit of movement somewhat ineffective. But now with the digital servos which operate at full torque even near center, my guess is that people running an arm MIGHT...just MIGHT use slightly more expo on their rudder to offset the mechanical negative expo. That’s if they really notice it.<br> <br> I just go for the bling. :)<br> <br> -M<br> <br> <br> On 5/9/08 9:24 AM, "chris moon" <<a href="mailto:cjm767driver@hotmail.com">cjm767driver@hotmail.com</a>> wrote:<br> <br> </span></font></font><blockquote type="cite"><font size="4"><font face="Tahoma, Verdana, Helvetica, Arial"><span style="font-size:10pt">I was going to put real diamonds around the edge of the wheel and a neon light below it...does that count?<br> <br> <br> Mark Atwood wrote: <br> </span></font></font><blockquote type="cite"><font size="4"><font face="Tahoma, Verdana, Helvetica, Arial"><span style="font-size:10pt"> Re: [NSRCA-discussion] Rudder pull-pull </span></font><font face="Calibri, Verdana, Helvetica, Arial"><span style="font-size:11pt">You have a problem with Bling???
